toaster: fix pylint errors

Prompted by issues discovered during running pylint on
the toaster sources, this patch fixes:

* missing import in toaster ui
* improper call of function in toaster ui (logger.debug)
* improper function definitions in bbcontroller
* invalid references to objects in bldcontrol.models
* proper initialization of object fields in ToasterTables

Also inhibiting specific pylint errors in files where
the problems are mis-identified.
